The age of the Lingkou archaeological site, Lintong, Shaanxi, is about 7300-6220 a BP and the Late Stage Yangshao Culture. The remains presented as 157 individuals belong to 13 spicies: Rhizomys sinensis, Hystrix hodgsoni, Nyctereutes procyonoides, Meles meles, Moschus sp. , Cervus hortulorum, Elaphurus davidianus, Caprinae, Gazella sp. , Bovinae, Sus domesticus, Phasianidae and Cyprinoid. Those vertebrate remains can be divided into 5 layers. During 7300-6930 a BP and 6600 - 6420 a BP plenty of browsing cervid fauna occurred, showing an obviously warm and humid climate condition. The faunas between 6930-6660 a BP and 6420-6220 a BP are different distinctly from 7300 - 6930 a BP and 6600-6420 a BP, and animals living in steppes became dominant. The evolution of the faunal ecological sequence during the stages indicates that the natural environment was interchanged from semiarid veldt to dry steppe, and gradually to the modern climate.
